Make Smart Driving Technology Closer to the People Deep Blue SL03i Smart Driving Experience

　　The word "volume" is the most distinctive label in today’s automobile industry. At the moment when the automobile market is scrambling to occupy the forefront of the market, the competitive direction of many cars is not only to configure the volume value, but also to be intelligent. However, many domestic new energy vehicles, such as ACC adaptive cruise system, have become standard, and the direction of the next volume of the car company is bound to be some more advanced intelligent driving assistance systems.

　　I, born in the all-electric digital platform, has four technical characteristics, such as high efficiency, high performance, high intelligence and high security. With high intelligence, it also has a high-level intelligent driving assistance system. The biggest difference between it and the general intelligent driving assistance system is that it has added a higher-level integrated adaptive cruise enhanced version and high-speed pilot intelligent driving assistance function, and the more detailed driving assistance action details from point A to point B. What will its performance be like? In the magic mountain city of Chongqing in 8D, let’s experience it.

　　On the deep blue SL03i, how about the hardware of Zhijia?

　　The dark blue SL03i we test-drive is equipped with a variety of sensing components, including 5 millimeter-wave radars, 12 ultrasonic radars, 6 micro-touch sensors, high-precision satellite system, capacitive touch-sensitive steering wheel sensor, 10 smart cameras with different pixels and different viewing angles inside and outside the car, and a DMS camera. Obviously, this is a low-cost intelligent driving hardware scheme that is not pure vision or laser radar. The cooperation of various sensing components can give full play to their respective advantages and realize 360-degree all-round monitoring.

　　In addition to hardware, the intelligent driving system of Deep Blue SL03i not only provides conventional maps and high-precision maps provided by Gaode, but also has a large-scale data pool. Based on a large number of open road tests, a large number of data accumulation and simulation training, as well as continuous optimization of algorithms and integration of software and hardware, the paper parameters and actual experience of this system can achieve a good result.

　　Deep blue SL03i has both traditional dashboard and AR-HUD. Its imaging size is equivalent to 53 inches, and the information that can be displayed here is very basic but critical. More finely on the central control screen, it shows the surrounding road conditions very accurately. Vehicles, lanes and obstacles will be displayed, all thanks to the capture and identification of the surrounding environment by the on-board hardware system.

　　The car system supported by Qualcomm Snapdragon 8155 can provide more critical computing power for intelligent driving. In addition to the highly intelligent IACC-L integrated adaptive cruise enhanced version, it is also equipped with NID pilot intelligent driving assistance system, which is a set of driving assistance system based on navigation path. It relies on high-precision maps to achieve pilot-assisted driving on supported expressways and some urban express sections, and it can achieve pilot-assisted driving from point A to point B on the road, which can achieve more advanced self-driving.

　　Our experience just happened to catch up with Monday, and it was still in the mountain city of Chongqing, which is known as the 8D magic city and may be the most complicated road network in the world. The experience of assisted driving on such complicated and changeable road conditions with dense traffic and frequent road construction is a great test of the intelligent driving skills of Deep Blue SL03i. In fact, except for some high-speed sections, the occasional urban road conditions in Chongqing also intermittently support the coverage of high-precision maps. So what is its actual performance here?

　　Urban Expressway+Expressway Intelligent Driving Experience

　　Under ideal conditions, this intelligent driving system of Deep Blue SL03i can make the vehicle travel from point A to point B automatically according to the route set by navigation. In this process, it can not only overtake the slow-moving vehicle, avoid danger, but also choose a better route independently. The experience is actually very close to automatic driving. However, it should be noted that under the current technical level and the requirements of laws and regulations, all functions are only auxiliary, and the driver can’t be the shopkeeper of cutting.

　　Specific to IACC-L, the operation of activating the system is very simple. When the vehicle drives to a road covered by a map, a steering wheel icon will pop up on the dashboard to remind you that you can turn on the function. After turning on, the vehicle can automatically drive according to the destination set by navigation. In actual use, the IACC-L startup operation of Deep Blue SL03i is quite simple. Like most cars, the system can be successfully activated by continuously dialing the electronic gear twice after being prompted, and the adjustment of the following distance and speed can be completed through the buttons on the left side of the steering wheel.

　　It is worth mentioning that in Chongqing, where traffic jams are frequent, when the driver turns on the function setting of high-speed pilot intelligent driving assistance or integrated adaptive endurance assistance, the gear will be the lowest gear "1st gear", so the following distance will be more in line with the driving habits of actual users. Officials say that the minimum following distance in this state can be controlled at 2m, and it is more difficult to be "jammed" by other vehicles.

　　The area covered by high-precision map on high-speed will display the red stamp of "NID" on the map, and when driving here, the system will automatically switch from IACC-L integrated adaptive cruise enhanced version to NID high-speed navigation assistance. Compared with the integrated adaptive cruise enhanced version, the biggest difference of this high-speed navigation aid is that it can realize automatic ramp up and down and route planning. On the expressway, its function is basically the same as that of automatic driving.

　　This system can automatically realize the self-adaptive cruise with lane centering and intelligent adjustment with the car, and realize automatic or commanded steering and intelligent deceleration by identifying speed limit signs in qualified corners. Its logic of judging and responding to the action of the preceding car is very old for drivers, so you don’t have to worry that any deceleration action of the preceding car will make your car have a huge nervous reaction.

　　Not all traffic participants on the road follow the rules. Facing the sudden sideways situation, the car can always try its best to avoid it at the first time. Deep blue SL03i can comfortably control the vehicle to slow down to a safe speed according to the speed limit signs appearing in tunnels/ramps/bends. Like an old driver, he will try his best to stick to the edge of the lane to make a smart shift, or try his best to brake and slow down, so as to prevent problems to the greatest extent, but he will never use the bypass to avoid obstacles.

　　The timing of intelligent lane change is optional, and it is cautious under standard conditions. When there is no car on the right rear, its lane change action is very textbook, and the timing and speed of lighting, turning and merging are very regular. However, in Chongqing, the car will only change lanes when the rear side is safe and the conditions are met. The threshold is similar to that of drivers who leave the novice period. The game is rather timid. In case of special circumstances, it will make timely corrections during the lane change process, keep a relative distance from the preceding car, and then accelerate the distance after completing the lane change.

　　When the speed of the preceding vehicle is too slow and there is road space on both sides, the system will judge the traffic situation and decide whether to change lanes and overtake. It is also optional. Under normal circumstances, its automatic lane change does not require a long safety margin, and the requirements for the distance between the front and rear vehicles on both sides of the lane are not great. The decision logic of the system is very human, and the timing is very human, and there will be no problem of frequent and urgent lane change.

　　Occasionally, on particularly congested roads, the logic of the system actually puts safety first. In the face of crowded congested roads and other vehicle drivers without zipper traffic habits, the system will occasionally appear indecisive, and the response of the system will appear a little twitchy. When the car is implemented, there will be a big swing or pitching action, but even the old driver will not be able to handle this scene well.

　　The system is also skilled in the choice of roads in and out of the ramp. According to the map and congestion, it will change to the exit lane in advance. When passing through the ramp, the overall response of the car is very decisive, and the speed will also drop to a reasonable range. The overall performance is very sophisticated, and it gives you enough confidence. You don’t have to worry about the problem that the curve with large curvature can’t turn around or snake back and forth in the lane to correct the driving direction.

　　In the case that the continuous off-ramp intersection may be missed continuously, deep blue SL03i can accurately judge the congestion intention of other cars, and can choose to slow down and yield independently on the premise of safety. Deep blue SL03i can monitor and predict the behavior of surrounding vehicles in real time during the process of traffic jam and the import and export of the intersection ramp, and always merge the vehicles as safely as possible until you are reminded that you must take over manually.

　　When passing through some ramps with narrow radians, the dark blue SL03i can also drive in and out very calmly, and the steering wheel turns silky all the time, and there is almost no line pressing, and the whole acceleration and deceleration are controlled properly, so as to avoid the uncomfortable feeling of the drivers and passengers pitching back and forth and swinging left and right, and bring users a smooth and stable driving experience.

　　The high-speed navigation system is based on the coverage of high-precision maps and services, and in areas not covered by high-precision maps, the system will automatically downgrade to the mode of integrated adaptive cruise enhanced version and remind drivers to be alert to safety, and then the integrated adaptive cruise enhanced version will automatically upgrade to high-speed navigation assistance as long as it drives into the road section with high-precision maps that meet the service coverage again.

　　Summary:For today’s experience, most of the time we experience is on the expressway or expressway in Chongqing. Although it seems simple, considering the complexity of Chongqing’s own traffic, it is really not a simple thing to handle such a scene well. The deep blue SL03i does ensure both safety and traffic efficiency in most of the time, which is quite surprising.

　　What needs to be considered is that, judging from this set of intelligent driving ability, its performance this time does not lose some models that focus on high-level intelligent driving at a price of 300,000 yuan, and even has certain advantages in details. Considering the starting price of Deep Blue SL03i, no matter which way it goes public in the future, the price will make technology equal, which is probably its greatest advantage.
